Never marry your bias. Yeah, at times in crypto Shorting can be very profitable.
But, when you do it for so long, when it starts to reverse, you won't even see it, trust me.
Soon, you have a bull run and you still try to short things and you could have long it but you are married to your bias.
Next thing you know, you are in denial phase, just trying to short while the price is going up, up3x, up5x and you still try to short.

So, be very careful, market works in both directions
